Abstract
A device for securing an object to a ceiling includes a threaded rod, a bracket and a spring-loaded tab. The spring-loaded tab has a tab portion with an outer surface. The tab portion is rotatable about an axis perpendicular to the threaded rod. When the device is attached to the object and the object moves into an opening in the ceiling for installation to the ceiling, the tab portion is urged from an extended position to enable the object to pass through the opening. Subsequently, the tab portion returns to its extended position such that the object can be temporarily supported by the tab within the ceiling opening. The bracket is configured so that during a removal process, a portion of the bracket urges the tab portion inward from the extended position to enable the object to be removed from the ceiling opening.
